An iPhone app needed 23,000 free downloads per day to reach spot number 50 in the top Free charts in the Apple App Store, says mobile app analytics firm Distimo, based on research performed during the month of May 2013 aimed at discovering what it takes to break into the App Store’s top Free, Paid, and Grossing charts. For paid applications, that number was 25 times lower, at 950 downloads. Meanwhile, to reach the #50 spot in top Grossing charts, an app needed daily revenue of $12,000.
